IMPROVEMENT IN COB-SEPARATORS FOR CORN-SHELLERSA.

Specification forming part of Letters Patent No. 146,245, dated January 6,1874; application filed October 18, 1873.

To all whom t may. concern:

Be it known that we, THOMAS A. GALT and GEORGE S. TRACY, of Sterling, in the county of Whitesides and State of Illinois, have invented a new and valuable Improvement in Cob-Separators for Oorn-Shellers; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a sectional view of our separator. Fig. 2 is a plan view of the same.

`This invention has relation to the separation of cobs from shelled corn while the saine are being delivered from a corn-Sheller; and it consists in combining with a grated bed a series of arms, which are arranged to revolve through this bed and throw oil' the cobs beneath a iiexible apron, while the grains of corn pass ireelythrough the bed and are collected in a suitable receptacle, as will be hereinafter explained.

The following is a description of our invention: In the annexed drawings, A represents the box or hopper, in which the cobs and shelled corn are received from a corn-Sheller; and B B represent legs on which this box is mounted. The box A is constructed with an inclined feed-board, C, and an inclined grate, D, which latter is composed of `parallel bars, in'clining from an opening, a, for the discharge of cobs, to the lower end of the feed-board O. Beneath the grate D is a horizontal transverse drum, E, from which radiate a number of arms or teeth, b, which extend up between the gratebars` a suitable distance to throw the cobs out through the opening a., when rotated in the direction indicated by the arrow in Fig. 1. One end of the shaft of drum E extends through the box A and receives a pulley, c, on it, to which motion is given Aby means of a belt, d, which is passed around a pulley, e, on a shaft driven by any convenient means. The opening a, at the highest end of the grate D, has a flexible apron or curtain, g, applied to it, which is slitted vertically, and intended for allowing free exit to the cobs, but preventing the expulsion of the shelled corn.

Our separator is applicable to corn-shellers of various kinds, and when it is arranged for operation the box or hopper A will receive the cobs and the shelled corn. When the drum E is rotated, the arms or teeth b will have hereunto subscribed our names in the presence of two witnesses.
